NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-docs package and not the postgresql-docs package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The PL/perl and PL/Tcl implementations in PostgreSQL 7.4 before 7.4.30, 8.0 before 8.0.26, 8.1 before 8.1.22, 8.2 before 8.2.18, 8.3 before 8.3.12, 8.4 before 8.4.5, and 9.0 before 9.0.1 do not properly protect script execution by a different SQL user identity within the same session, which allows remote authenticated users to gain privileges via crafted script code in a SECURITY DEFINER function, as demonstrated by (1) redefining standard functions or (2) redefining operators, a different vulnerability than CVE-2010-1168, CVE-2010-1169, CVE-2010-1170, and CVE-2010-1447.
